DISPENSING-VALVE.

Specification of Letters Patent.

Patented Apr. 8, 1919.

Application filed February 11, 1919. Serial No. 276,314.

To all whom it may concern:

Be it known that I, WILLIAM E. LEIBING, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Dispensing-Valves, of which the following is aspecification.

The present invention relates to a dispensing faucet adapted for use for the dispensing of two or more intermixed liquids or where it is desired to dispense separate charges of different liquids, the dispensing being dependent on the direction of operation' of the controlling handle of the faucet.

The invention has for its principal objects to provide a construction wherein the valve is spherical in form and is capable of op crating within a socket or chamber in different planes at right angles to each other, whereby a plurality of fluids may be dis-' pensed according to the direction of movement of the valve; one wherein a novel construction of casing is provided; permitting a ready take-up of wear of the valve packings; one wherein a sheet metal housing incloses the casing and shank for attachment to the casing support, whereby the finishing of the exterior surface of the casing is not required, thereby permitting of the construction to be cheaply made.

lVith the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, struction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of theinventiou.

To more fully comprehend the invention, reference is directed to the accompanying drawings, wherein-.-

Figure 1 is a view in vertical section of the preferred embodiment of my invention.

Fig. 2 is a view in front elevation with the valve housing and casing partly broken away.

Fi g. 3 is a bottom plan view of the upper size and minor details of conportion of the valve casing with the finishing sheath removed therefrom.

Fig. 4 is a top plan view of the upper portion of the valve casing with the finishing sheath removed therefrom.

Fig. 5 is a detail view in rear elevation of the upper portion of the valve casing with the sheath removed therefrom and illustrating certain of the channels in the peripheral surface thereof.

Fig. 6 is a diagrammatic plan view of the valve illustrating the various bores therein.

Fig. 7 is a view in side elevation illustrating the various bores extending through the, valve.

Fig. 8 is a bottom plan view of the valve, illustrating the bores therein.

In the drawings, 1 indicates a receptacle or base to which issecured one end of a tie rod or supporting arm 2. Carried on the outer end of the supporting arm 2 is a valve casing consisting of the members 8 and 4, the member 3, as in Figs. 1 and 3 of the drawings, being in the form of a ring and having at one side an extension 5 which is also circular in plan, the face of which is in the form of a disk, and into the center of this disk or extension 5 threads the outer end of the member 2. The underface of the member 3 is provid d with anannular interiorly threaded recess or depression 6, into which is received the upper threaded end 7 of the member 4 which terminates in a downwardly disposed discharge spout 8.'

cal valve seat 9, a portion of which sphere is formed in the member 3 above the depression 6, and the cooperating portion is formed in'the upper end of the member 1.

The extension 5 is formed with the bores 10, 11 and 12, which connect respectively through the pipes 13, 14 and 15 with a plain water supply and charged water supply, and a supply of syrup, although it is apparent that different liquids may be passed through said pipes should the device be employed for other purposes thanthe dispensing of beverages.

The exterior surface of the member 3 is formed with the respective grooves 16 and 17 which extend partially around the same,

and the exposed wall of which is covered by a plate 18 soldered in position over the sides of the grooves. One end of the respective grooves connects through the respective channels 19 and 20 with the respec tive bores 10 and 11, and the opposite ends of said channels terminate as at 21 and 22 on the inner surface of the spherical valve the bores 21, 22 and 23 is a groove 24 having inwardly. converging side walls, and within each of said grooves surrounding the respective bores is positioned a gasket or washer 25, the surface of which projects a slight distance inwardly from the inner surface of the seat 9.

Surrounding the upper end of the channel 26 of the discharge spout 8 and projecting inwardly beyond the inner surface of the spherical seat 9 is a gasket or packing member 27 of any suitable material.

The members 3 and 4 are surrounded or inclosed by a finishing casing or sheath of any suitable construction, but illustrated as consisting of the lower sheet metallic mem ber 28 which incloses the lower valve casing member 4 and the upper sheet metallic member 29 which incloses the upper member 3, and extending from said member are the sleeves 30 which surround the pipes 13, 14 and 15 and extend to a point to contact with the surface of the member 1. The meeting edges of the members 28 and 29 are finished or concealed by an overlapping head 31 formed on the lower edge of the member 29 and the front portion of said sheath is protected or covered by a suitable name plate 32 secured in position by screws 33, one of which extends through each of the members 28 and 29.

The discharge spout 8 is formed with an annular flanged depression 34 in which is received the lower edge of the sheath 28 surrounding the lower portion of said casing and the upper portion of said spout, which construction permits of the upward threading of the lower portion of the valve casing to maintain the valve hereinafter described tlghtly seated wlthin sald caslng.

To break the vacuum within the outletor discharge opening 26 of the spout 8 to permit the drain of liquid trapped therein, said spout is formed with a vent or duct 36 downwardly extended through the wall thereof with its u er end terminatin in.

the chamber 37 surrounding the upper'portionof said nozzle and 'formed between the interior wall surface of the sheath 28 and the exterior surface of the upper portion of the nozzle 8, and the outer surface of the casing member 4. This opening also permits the draining through the nozzle or discharge spout of any seepage which might escape into the chamberv 3 Within the spherical valve seat 9 is mounted for universal swinging movement a spherical valve member 38 from the surface of which extends an operating stem 39 projecting upwardly through the opening 40' in the upper casing member 3. A plate 41 positioned over said opening 40 and formed with the right angularly disposed intersecting'guide slots A, B, C and D provides a guide through which the operating stem 39 passes during the operative movement of said valve, and when said stem is disposed at the intersecting portion of said guide slots, as 1n Fig. 4 of the drawings, the ports of said valve hereinafter described do not communicate with any of the channels in said casing, the valve then being in what may be termed closed position. The stem '39 carries a finishing casing 42, the loweredge of which is adapted to operate during the swinging movement of said stem over the outer surface of the upper finlshing sheath 29, which is also formed with intersecting slots or channels which lie directly above the slots A, B, C and D. The upper end of the stem 39 is finished with a spherical operating handle 43, preferably held thereon by a retalning screw 44.

Referring to Figs. 6, 7 and 8 of the drawings, the channels within the spherical valve 38 are designated by different broken lines.

Each of said channels opens at one endabove the horizontal transverse center of the valve. and at their lower ends open preferably below the horizontal transverse center of said valve, and when said stem 39 of the valve is in a perpendicular position, as in Figs. 6 and '7, the communication of said channels with anyof the ports of said casing is cut ofi'.

On the movement of the stem 3.9'within the uide slot B, Fig. 4 of the drawings, a

mixture of different fluids is discharged from the nozzle 8, in the present construc-. tion it being a combination of syrup and water. The syrup enters the valve from the port 23 into the upper end of a channel 45' disposed angularly in a downward plane in the valve and termmatmg 1n an outlet ordischarge opening 46.

The water to intermix with the syrup is admitted from the port 22 into the open end 47 of a channel 48Vwhich intersects the channel 45 adjacent its upper end. Thus when in this position an intermixed stream of syrup and water is discharged from the nozzle 8.

It will be observed that the syrup channel is of a larger diameter than the channel 48, and when it is desired to vary the volume of syrup adapted to intermix with the water,. the same is accomplished by the adjustment of a collar 49 threaded to the member 5, which adjustment limits the depth of reception of the stem 39 in the guide slot B.

To obtain a coarse stream of charged water which is desirable in admitting into a glass of beverage after thesyrup has been supplied, the stem 39 is moved from the slot B to its perpendicular position and then is swung laterally into the slot A. This movement interrupts the connection of the channels 45 and 48 with their respective ports 23 and 22 and positions the upper end of a channel 50 in communication with the discharge port 21 and also positions the lower enlarged discharged end 51 of said channel 50 in communication with the bore 35 of the discharge nozzle 8.

As in Figs. 6 and 8 of the drawings, the lower end 51 of this discharge channel 50 is enlarged, and within said enlargement is positioned a screw or member 52 which causes a diffusing of the stream issuing therefrom in the mixing of the syrup with the charged water supplied to the receptacle. When it is desirable to admit as a mixing stream into the receptacle a fine or mixing stream of charged or carbonated water under pressure, and to accomplish this the stem 39 is removed from the slot A to perpendicular position which breaks the connection between the channel 50 and port 21 and the stem is thence moved into the slot D. This movement of the stem into the slot D causes a registering of the upper end of a channel 53 with the port 21 and positions the contracted discharge end 54 of said channel in communication with the bore 35 of the nozzle 8, thus permitting the supplying of a mixing stream under pressure to the\ receptacle containing the beverage, and which is supplied until the syrup is thoroughly intermixed with the carbonated water.

Should, for any reason, it be desired to draw a glass of plain water from the dispensing faucet, the stem 39 from perpendicular position is moved into the slot C, which causes a lateral oscillating movement of the valve and positions the upper end 55 of a channel 56 into communication with the port 22 and the lower end of said channel 56 into communication with the bore 35 of the nozzle 8.

It will be apparent that the present valve is capable of operation in intersecting planes arranged at right angles to each other, and when the stem thereof is at the point of intersection of said planes of movement the supply of fluid through the nozzle 8 is cut off. It is possible, by this construction, to

move the valve whereby a charge of plain water and syrup, a charge of carbonated water, a fine mixing stream of carbonated water or a stream of fresh water is obtainable, and it is not required in the operation of the valve to obtain any of these streams that the valve be moved to cause the ports to pass through a movement which would momentarily admit another stream into the nozzle 8.

It will be apparent that the adjustment of the lower section 4 of the casing forces the upper spherical portion of the nozzle against the packings 25, which are distrib-- uted at equidistant points over the upper surface of said valve, and thus prevent leakage between the ports surrounding said packings and the ports in said valve.

A guide pin 57 extending inwardly into the valve receiving chamber 9 projects into a vertical groove 58 formed in the outer surface of the valve 38, which pin operating in the groove assists in guiding the valve in its movements and prevents rotation of the same axially with the spindle 39.
